Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2065SS1G40 is determined by the following critical parameters:

Circuit and Electrical Compatibility:

• SPDT circuit configuration (mandatory match)
• On-On switch function (mandatory match)
• Current rating of 0.4VA AC/DC (mandatory match)
• Voltage rating capability must meet or exceed 28V AC/DC

Mechanical and Physical Compatibility:

• Panel mount orientation: Right angle, vertical rear mounting
• Termination style: PC Pin
• Panel cutout dimensions: Circular 6.50mm diameter (or compatible within tolerance)
• Actuator type: Plunger for cap or equivalent button configuration

Environmental and Compliance Requirements:

• Operating temperature range must encompass or exceed -30°C ~ 85°C
• RoHS3 compliance required
• Electrical life minimum 50,000 cycles

The substitute part 8161SHAV2BE2 meets the core functional requirements of SPDT circuit, On-On function, 0.4VA current rating, and PC Pin termination. However, specific parameter variations exist that must be evaluated for application suitability.

Parameter Comparison

Engineering Selection Recommendations

The 8161SHAV2BE2 from C&K provides functional equivalence to the obsolete MB2065SS1G40 for SPDT pushbutton switch applications. Both components share identical circuit configuration, current rating, and electrical life specifications, with matching PC Pin termination and panel mount orientation.

Voltage Consideration: The substitute part is rated for 20V AC/DC maximum, compared to the main part's 28V rating. Applications operating at or below 20V are fully compatible. Applications requiring 28V operation must evaluate whether the lower voltage rating of the substitute presents a constraint.

Temperature Consideration: The substitute operates across -30°C to 65°C, versus the main part's -30°C to 85°C range. Applications requiring operation above 65°C must assess thermal requirements independently.

Panel Cutout Dimension: The substitute requires a 6.35mm diameter circular cutout versus 6.50mm for the main part. Existing panel designs with 6.50mm cutouts may require mechanical adaptation or panel modification.

Compliance Status: Both components are ROHS3 compliant. The substitute is currently in active production status, ensuring ongoing availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the 8161SHAV2BE2 directly replace the MB2065SS1G40 in all applications?

A: Direct replacement is possible for applications operating at 20V or below. For circuits designed for 28V operation, the substitute's lower voltage rating must be evaluated against actual circuit requirements. Panel cutout dimensions differ slightly (6.35mm vs 6.50mm), requiring mechanical assessment.

Q: What is the primary difference between these two switches?

A: Both switches share identical SPDT circuit configuration, On-On function, and 0.4VA current rating. The main differences are voltage rating (28V vs 20V), maximum operating temperature (85°C vs 65°C), and panel cutout diameter (6.50mm vs 6.35mm).

Q: Is the substitute part suitable for high-temperature applications?

A: The 8161SHAV2BE2 operates to 65°C maximum. Applications requiring operation above 65°C should not use this substitute without independent thermal analysis.

Q: Will the substitute fit existing panel cutouts designed for the MB2065SS1G40?

A: The substitute's 6.35mm cutout diameter is slightly smaller than the original 6.50mm specification. Existing panels may accommodate this difference, but mechanical fit should be verified for each installation.

Q: Are both parts RoHS compliant?

A: Yes, both the MB2065SS1G40 and 8161SHAV2BE2 are ROHS3 compliant.

Q: What is the availability status of each part?

A: The MB2065SS1G40 is obsolete with limited existing inventory. The 8161SHAV2BE2 is in active production, providing reliable long-term availability for new designs and ongoing supply requirements.
